Problems solved by technology

However, the cost of natural stone mining has been rising as the controls on natural stone mining have been tightened
[0003] Moreover, absorbing the radiation of zircon sand or zirconium silicate by adding radiation-absorbing substances to the bottom glaze layer may reduce the whiteness of the bottom glaze layer of the crystal diamond flashing ceramic slab, thereby reducing the reflectivity of the bottom glaze layer, making reflection to The light in the glitter layer is reduced, thereby reducing the sparkle effect of the ceramic slab

Abstract

The invention belongs to the technical field of ceramic tile manufacturing, and particularly relates to a ceramic rock plate with glittering crystal diamonds and a preparation method of the ceramic rock plate. The ceramic rock plate comprises a green body layer, a ground glaze layer, a pattern layer, a protective glaze layer and a flashing glaze layer, the ground glaze layer comprises zirconium silicate and lead-containing ceramic waste, and the flash glaze layer comprises zircon sand. The lead-containing ceramic waste is introduced into the ground coat layer, irradiation caused by adding a large amount of natural zircon sand to the glaze surface can be effectively reduced by means of the ray absorption characteristic of lead, meanwhile, the lead-containing ceramic waste is good in stability and does not affect the ground coat whiteness of the ground coat layer, and therefore the reflective rate of the ground coat layer is guaranteed, light reflected to the flash layer is guaranteed, and the service life of the flash layer is prolonged. Therefore, the flashing effect of the ceramic rock plate is guaranteed. The whiteness of the ground coat of the ground coat layer of the prepared ceramic rock plate with the glittering crystal diamonds is greater than 90, the internal illumination index is lower than 0.4, and the external illumination index is less than or equal to 0.5.

Description

technical field [0001] The invention belongs to the technical field of ceramic tile manufacture, and in particular relates to a ceramic rock slab with crystal diamond flashing and a preparation method thereof. Background technique [0002] With the rapid development of ceramic slabs with imitation natural stone effects, ceramic slabs with crystal diamond flashing effects are favored by the terminal market. The crystal diamond flashing rock slab mainly introduces special large-grained zircon sand into the glaze layer as the flashing point, and forms a flashing effect by means of reflection or refraction of light on the polycrystalline surface of the zircon sand. In order to enhance the flashing effect, generally a large amount of zircon sand is added. Since natural zircon sand is associated with radioactive elements such as uranium and thorium, a large amount of zircon sand will increase the radioactivity of the product. At the same time, a large amount of zirconium silicate...
